高频离子源形成的HD+离子束中H3+比例实测研究

HD+在是研究分子离子同位素效应等方面最简单和理想的离子，并且在天体物理等领域有重要应用。但在实验测量其核间距和结合能研究中不可避免会混入H3+从而对实验结果产生影响. 本文在实际测量获取产物各种物理量的基础上，采取对比与分析的反推方法, 将离子源中两种离子的比例实际测量出来, 从而能较为准确地研究HD+的结构和性质. 将实验测量的结果与理论推算进行比较, 得到了相对较好的结果。

Measurement On the ratio of HD+ and H3+ in hydrogen mixed gas ion source

The molecular ion HD+ is important in the astrophysics and astrochemistry study, but in the experimental detection and measurement, the experimental results of HD+ may be influenced by the inevitable mixing with H3+. This paper adopts the method of comparison and analysis of Coulomb explosion products. The proportions of the two kinds of ions are obtained in HF ion source, which can reach more accurate study on the structure and properties of HD+. The relatively good results can be obtained by comparing the experiment results with theoretical calculations. This method will provide a useful reference and inspiration for similar researches.
